Just asked ULA where the "bottle holsters" were going to be located, and whehter they would interfere with the bellowed side mesh pockets. Their answer is: "The side mesh pockets are a standard feature on all ULA Packs. The optional bottle holsters are positioned on the shoulder straps. Images will be posted shortly to better illustrate their position and function."

I suspect they will be something like GoLite's reflective webbing strap with velcro to hold part of the bottle, along with an elastic cord with spring lock to hold another part. Works great with bicycle water bottles, but something to be desired for Nalgene type bottles.

the bottle holsters are just two pieces of shockcord w/ a cordlock. there are two per side. brian says that they work best w/ the taller bicycle water bottles. but i use just one strap per side and use the small gatorade water bottle. the shockcord goes attaches to the shoulder strap where the d-ring is. check it out hear: http://img401.imageshack.us/img401/4567/pb2100240sd.jpg

>>"Not sure about the front mounted Water Bottle Holster even at 0.4oz"

just curious. why? i've added them to packs and used them w/o a problem. AR's use them all of the time - and they often move a lot faster than most of us. i'm sure you have a good reason for your statement. what are you thinking of, that i've missed?

I've spoken to Brian on several occasions. ULA is an excellent business model for the UL cottage industry. Excellent Product, Excellent Customer Service, Excellent Turn Around On Orders. Everything I’ve ordered has exceeded my expectations. And he’s a Great Guy too, if you have any questions or concerns Brian makes the time to talk to you.
